    Answer: 74.8m

    Explanation:

    We have the vector defined by:

    r = 101m

    θ = 42.2°

    When we want to write this as rectangular components, we have that:

    x = r*cos (θ)

    y = t*sin (θ)

    this is because we can construct a triangle rectangle, where the module of the vector is the hypotenuse, the x component is the adjacent cathetus and the y component is the opposite cathetus.

    Then, here we have that the x component is

    x = 101m*cos (42.2°) = 74.8m
